Another open issue is the threat to limit amateur radio access to the 60-meter band (shared with commercial interests).<p><a href="https:&#x2F;&#x2F;www.arrl.org&#x2F;news&#x2F;deadline-extended-to-november-28-2023-for-60-meter-comments" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.arrl.org&#x2F;news&#x2F;deadline-extended-to-november-28-2...</a>

So what sort of symbol rate becomes theoretically possible within a HF frequency band?

Are you allowed to use phase to double or quadruple the effective signal &quot;density&quot; in the bandwidth? Or, is that part of the 2.8khz no matter how you &quot;time&quot; it?<p>(Not a ham. In microwave point to point space, you can usually get two customers on a direction by exploring the space around the 360 clock for angle&#x2F;phase of the signal being sent, horizontal vs vertical is not uncommon)
